Yeah, I gotta back Salty on this one.
The Utes did lose to USC on the last play of the game.
You can argue (I'm guessing this is your rationale) that USC was ahead before the play, and ahead after the play. That's true. But, Utah started that final play with possession, and the opportunity (and a fairly good one a that - not a hail mary type chance) to win or tie (and go to overtime with momentum) with that play. Thus, the game was lost on the final play.
But it's certainly possible to sit here and split hairs. The fact of the matter is, USC won. But they did not dominate Utah all game long. Utah mad a very close game out of it.
